swift同樣可以實現(xiàn)OC中AFNetworking+MJExtension的效果，實現(xiàn)方法是Alamofire+SwiftyJSON+HandyJSON
Alamofire：網(wǎng)絡(luò)請求
SwiftyJSON：數(shù)據(jù)解析
HandyJSON：映射為model
一、獲取SessionManager子類的單例
節(jié)約系統(tǒng)開支不用每次網(wǎng)絡(luò)請求都生成一個SessionManager子類對象

三、使用
新建model類
//
// TMMineModel.swift
// ivygateSwift
//
// Created by 紀(jì)志剛 on 2018/4/24.
// Copyright ? 2018年 紀(jì)志剛. All rights reserved.
//
import UIKit
import HandyJSON
class TMMineModel: HandyJSON {
var code:String = ""
var name:String = ""
var domain:String = ""
var captcha:Bool = false
//HandyJSON要求必須實現(xiàn)這個方法
required init() {
}
/// 獲取個人信息
///
/// - Parameters:
/// - succ: <#succ description#>
/// - fail: <#fail description#>
static func requestFun(succ: @escaping(_ arr:Array<TMMineModel>) -> (), fail: @escaping (_ errStr: String) -> ()) {
TMNetworkingTool.requestFun(url: "你自己的網(wǎng)絡(luò)請求", method: kHTTPMethodGet, parameters: nil, showLoading: false, succ: { (responseData, response) in
succ([TMMineModel].deserialize(from: responseData, designatedPath: "data") as? Array<TMMineModel> ?? Array.init())
}) { (errStr, err) in
fail(errStr)
}
}
}
使用方法
TMMineModel.requestFun(succ: { (model) in
print("網(wǎng)絡(luò)請求成功了")
}) { (errStr) in
print("失敗了")
}
image
可以看到網(wǎng)絡(luò)請求成功之后返回了一個數(shù)組，數(shù)組內(nèi)是自定義數(shù)據(jù)類型
HandyJSON用于數(shù)據(jù)映射時注意
- model類繼承自HandyJSON并實現(xiàn)init方法
//HandyJSON要求必須實現(xiàn)這個方法
required init(){}
2.重命名屬性時實現(xiàn)方法
func mapping(mapper: HelpingMapper) {
mapper <<<
self.ID <-- "id"
mapper <<<
self.Description <-- "description"
}
3.映射為model類和映射為model數(shù)組的用法分別為
TMMineSaleStatusModel.deserialize(from: jsonStr, designatedPath: kNet_data_Key) ?? TMMineSaleStatusModel.init()
[TMMineSaleStatusModel].deserialize(from: jsonStr, designatedPath: kNet_data_Key) as? Array<TMMineSaleStatusModel> ?? Array.init()
